【62 Macromolecular Chemistry and Physics】 Main-chain polyimidazolium polymers by one-pot synthesis and application as nitrogen-doped carbon precursors
This paper reports on the one‐pot synthesis of main‐chain imidazolium‐containing polymers, some of which show unusually high thermal stability. The imidazolium polymers are obtained by modified Debus–Radziszewski reactions for the chain build‐up from simple organic compounds, here pyruvaldehyde, formaldehyde, acetic acid, and a variety of diamines. The reactions are performed in aqueous media...

【41 Polymer】 Synthesis and linear rheological property of comb-like styrene-based polymers with a high degree of long-chain branching
A series of model comb-like polymers (PSVS-g-PS) with high branching degree were synthesized by nucleophilic substitution reaction between iodinated copolymer of styrene (St) with 4-(vinylphenyl)-1-butene (VSt) (PSVSI, backbone) and living polystyrene lithium (PSLi, side chain). This method is a facile way for modular synthesis of graft copolymers based on living anionic polymerization and hydrozi...

【10 Polymers for Advanced Technologies】 Effect of nanosized carbon black on thermal stability and flame retardancy of polypropylene/carbon nanotubes nanocomposites
Nanosized carbon black (CB) was introduced into polypropylene/carbon nanotubes (PP/CNTs) nanocomposites to investigate the effect of multi‐component nanofillers on the thermal stability and flammability properties of PP. The obtained ternary nanocomposites displayed dramatically improved thermal stability compared with neat PP and PP/CNTs nanocomposites. Moreover, the flame retardancy of resultan...

[Nature Chemistry] Photoswitching of Glass Transition Temperatures of Azobenzene-containing Polymers Induces Reversible Solid-to-liquid Ttransitions
The development of polymers with switchable glass transition temperatures (Tg) can address scientific challenges such as the healing of cracks in high-Tg polymers and the processing of hard polymers at room temperature without using plasticizing solvents. Here, we demonstrate that light can switch the Tg of azobenzene-containing polymers (azopolymers) and induce reversible solid-to-liquid transi...

33. Mechanically strong plant oil-derived thermoplastic polymers prepared via cellulose graft strategy
Abstract: The design of polymers from renewable plant oils is gaining more attention within sustainable development. Most plant oils based thermoplastic polymers exhibit poor mechanical properties. In this paper, we reported the mechanically strong cellulose-graft-soybean oil copolymers, which combined two natural biomasses in one. The soybean oil-based monomers with secondary amide groups (SOM1...

Preparation of Magnetic Hyper-Cross-Linked Polymers for the Efficient Removal of Antibiotics from Water
A novel method for fabricating magnetic hyper-cross-linked polymers (MHCPs) with high Brunauer–Emmett–Teller (BET) specific surface area, large pore volume, and good magnetic properties was developed. The synthesis process of MHCPs included two steps: the preparation of HCPs by external cross-linker and the in situ oxidation of the iron source in the structure of HCPs. On the basis of the system...

32. Highly efficient strategies toward sustainable monomers and polymers derived from fatty acids via tetramethylguanidine promoted esterification
Abstract: Three easily performed and efficient strategies for preparing sustainable monomers and polymers derived from renewable fatty acids were investigated. All of these strategies relied on highly efficient esterification between halogenated compounds and fatty acids promoted by 1,1,3,3-tetramethylguanidine (TMG). In strategy 1, fatty acid-derived monomers and polymers were synthesized by TM...

A Smart H2O2-Responsive Drug Delivery System Made by Halloysite Nanotubes and Carbohydrate Polymers
A novel chemical hydrogel was facilely achieved by coupling
1,4-phenylenebisdiboronic acid-modified halloysite nanotubes (HNTs-BO) with
compressible starch. The modified HNTs and prepared hydrogel were characterized
